A Boston court ruled in Blizzard's favor last week against a lawsuit brought on by Worlds Inc. (aka Worlds.com) that claimed the studio infringed on four patents that Worlds Inc. made in the mid-1990s.

This ruling is the latest development in a case that spans back to 2012, when Worlds Inc. filed the suit. The company claimed that Blizzard violated patents that showed the invention of "a method for enabling a first user to interact with other users in a virtual space," among other items. A U.S. District Judge ruled that these patents are invalid because those inventions already existed prior to the filings.

This isn't Worlds' first attempt to sue an MMO studio over these allegations, as it went after (and lost to) NCsoft and Linden Lab several years ago.

Twitter isn't a public company just yet, but its updated S-1 filing hit today and showed how it's grown in the last three months. While it showed 218 million monthly active users by the end of June, its Q3 stats have grown to 232 million (53 million of them are in the US). While the number of users accessing the service from mobile devices grew slightly from 75 to 76 percent, ad revenue on mobile grew 37 percent since the last report, compared to other revenue which was up 9 percent. It's making more money too, with revenue for the quarter of $168.6 million, up from $139 million in Q2 and $82 million for the same period last year. If you want to invest in the right stock at its IPO, look for TWTR on the NYSE -- until then prospective investors can dig through the financial data here and follow the @TwitterIR account for updates.

Less than a month after announcing its plans for an IPO, Twitter has today made its S-1 filing with the SEC public, offering the most detailed look yet at at the inner workings of the company. With the IPO, Twitter is looking to raise $1 billion on 472,613,753 shares of common stock, trading under the stock symbol TWTR.

In the filing, the company also confirmed that it now has 218.3 million monthly active users (or MAUs) according to its most recent numbers, and that it pulled in $253.6 million in revenue for the six months ending June 30th, 2013, an increase of 107 percent from a year earlier. According to the company, mobile users unsurprisingly account for a particularly big chunk of its business, with 75 percent of its average MAUs accessing Twitter from a mobile device in the three months ending June 30, 2013, and mobile use accounting for 65 percent of its advertising revenue. It still isn't making a profit, though, with the company seeing a net loss of $69.3 million for the aforementioned six month period. That's compared to $316.9 million in revenue for all of 2012, and a net loss of $79.4 million.

Of those 215 million MAUs, 49.2 million are in the United States, while 169.1 million are international, representing an increase of 35% and 47%, respectively, from the same period a year ago. Beyond those numbers, the company has also revealed the number of Timeline views for the first time; they stood at 150.9 billion for the three months ending June 30th, and 287.2 billion for six months prior (up 69% and 79% from a year earlier). On average, that translates to 691 timeline views per MAU for the same three month period, although that number jumps a fair bit looking just at US Twitter users -- they rack up 825 timeline views on average.

In a brief letter to shareholders included in the filing, the company says "Twitter represents a service shaped by the people, for the people," and that "the mission we serve as Twitter, Inc. is to give everyone the power to create and share ideas and information instantly without barriers," adding, "our business and revenue will always follow that mission in ways that improve-and do not detract from-a free and global conversation." Those interested in digging into all of the numbers can find the full filing on the SEC's website.

We've only seen hints of the Galaxy S4 Mini launching in the US through AT&T and Verizon, but a new FCC approval suggests that Samsung's mid-size smartphone could reach Sprint as well. The filing reveals an SPH-L520 device with both a Sprint-native LTE frequency and a body that's only slightly larger than the regular GS4 Mini. That sounds like a positive ID, although we won't make too many presumptions -- this could be a carrier-specific phone that happens to sport Mini-like dimensions. If the smaller Galaxy does arrive on Sprint, though, we won't be caught off-guard.

We're all in favor of advancing the state of the art, but there are times when we suspect that research is more about "what if" explorations than anything else. Exhibit A: Apple's new patent application for a wireless display. The concept would let a touchscreen detach from its laptop base through a 60GHz ultrawideband format (such as WiGig) and keep its battery powered up through at least some form of wireless charging located in the laptop's hinge. It sounds viable when others have experimented with wireless displays before, but we'd note that both technical realities and corporate philosophies might stand in its way. Along with the usual challenges of battery life and wireless range, Apple has so far argued that touchscreen laptops are unwieldy and isn't exactly in a rush to supplement booming iPad sales -- even if granted, the patent may just be a matter of covering the bases rather than any kind of roadmap for a two-piece MacBook Pro. Still, we won't completely rule it out when many also thought Apple wouldn't make a phone.

When Michael Dell signaled intentions to take his company private for an overhaul, there were questions as to just what he wanted to do if and when shareholders weren't watching his every move: was he going to shift attention away from PCs toward the enterprise? There's no reason to worry, according to a staff memo that his company has published through the SEC. Dell tells his employees that the firm will "significantly increase investment" in PCs and tablets after going private. While he's cryptic about what that means, he does note that there would be a shift away from valuing gross margins -- in other words, the company may take a hit on profits to make its device sales sing. Other strategies are more what you'd expect from any good business: more research and development, a simpler experience and a stronger push into developing markets like Brazil and China. We can't say we're completely surprised when Microsoft made an investment in Dell's reorg precisely to safeguard PCs, but it's good to know that Dell's interest in PCs still extends well beyond the server room.

We weren't kidding about that influx of FCC filings: the Verizon edition of Samsung's Galaxy S 4, the SCH-i545, has passed through the US regulator's approval right on cue. The device on display ticks all the checkboxes we'd expect, including LTE on both Verizon's main 700MHz band and the carrier's recently acquired AWS frequencies. We also notice HSPA-based 3G, which suggests Big Red's GS4 won't be a paperweight when abroad. The filing just leaves AT&T and T-Mobile as the major stragglers in the US; at the current rate, though, they'll have little trouble getting clearance before they have to fulfill any futureorders.

Sure, we've seen Sony dissect the Xperia Tablet Z to show its inner workings, but that doesn't get the slate any closer to its spring launch. An FCC approval will, however. The tablet has swung through the US agency in its regular WiFi form, with photos and a user manual removing any doubts as to its nature. While there are no surprises here -- not unless you really, really wanted to know the exact location of the WiFi antenna -- the move should leave just a few formalities between Americans and Sony's extra-thin design.

Going dual-screen is really the nuclear option for smartphone design -- it's what you use to draw attention when your regular, single-screen phones aren't thriving. We're at once unsurprised and appreciative, then, that BlackBerry has applied for a patent on a dual-screen phone concept that hasn't gone further than a filing. As shown, it would embrace the familiar concept of running separate apps on each screen, with a slight twist: it could recognize touch gestures that span both displays, such as a pinch to switch app positions. Naturally, it could recognize distinct gestures on only one side or put a keyboard on one display for typing on the other. Given BlackBerry's current designdirections and very different gesture concepts, the application is more of a what-might-have-been than any kind of roadmap. It's just as well when many twin-screen smartphones haven't exactly panned out.

The One Laptop Per Child team hasn't always been punctual -- see the XO 3.0, née XO-3 -- but it should be right on time with the XO-4. In step with March production plans, the ARM-based portable has passed through the FCC's approval in both conventional and touchscreen flavors. All models share 5GHz-capable 802.11n WiFi as well as Bluetooth; there's no cellular surprise lurking underneath, if you're curious. More than anything, the filing is good news for students in the developing world, who are that much closer to touchscreen laptops at a time when the technology is still fresh for just about everyone.

We've all seen That Person in the movie theater: the one whose compulsive texting guarantees a distraction for everyone through the bright screen. Microsoft might not change that disruptive behavior, but it could save us from noticing through a new patent application. The team in Redmond is exploring an "inconspicuous mode" that would dial down not just the screen brightness and sound, but also the information on the display -- it could remove a bright background and limit the number of attention-grabbing notifications. The technique could even detect certain conditions, such a very dark bedroom, and invoke the mode without having to ask. Like with most patents, we don't know if Microsoft plans to use the technology in earnest; we've reached out, just in case a similar mode has previously lurked in the background. When the patent filling is crafted with Windows Phone in mind, however, we wouldn't be surprised if some future version of the mobile OS learns to mind its manners.

Update: A Microsoft spokesperson did get in touch after our inquiry and confirmed that there hasn't been such a mode so far. We've also been reminded, as we mentioned, that Microsoft "regularly applies for and receives patents" and that "not all" of them will ultimately reach shipping products.

Sonos is the de facto choice for multi-room audio, but even some of its biggest proponents will grumble about the lack of built-in WiFi -- going wireless in any way has meant tacking a Bridge on to the cost of an already expensive system. An FCC filing for an upcoming device, the Playbar, hints that common sense might have the upper hand. While there's few details of the audio system itself, there's explicit mentions of dual-band 802.11n WiFi inside. Just what that WiFi does is another matter. Sonos prefers using its proprietary network to cut back on lag and interference, so the Playbar's additional wireless may extend functionality rather than simplify our lives. With approval out of the way, there's a better chance we'll know the full story in the near future.

Update: We've done some digging, and the WiFi may be more innocuous: Sonos' proprietary network is actually WiFi that's just invisible most of the time. Android users have access to settings that expose Sonos' WiFi network and make it usable. As such, the Playbar may be more conventional than first thought, although its exact role in the home is still a mystery.

The curved screens of Samsung's Nexus S and Galaxy Nexus helped them stand out in the smartphone crowd, but it's clearer than ever that the company doesn't have a lock on the idea. Apple is exploring the concept as well: it just received a patent for a technique that molds thin glass into bent or curved shapes without a drawn-out process or using risky chemicals. By having alignment tools shift along with hotter temperatures during a glass slumping process, where the material shapes itself around a mold, Apple can bend glass without any interference -- leading to curvy surfaces that are both quicker to make and higher quality. A patent doesn't mean that we'll see a curved iPhone in the immediate future, though. Apple leaves its options open and suggests that anything from mice to TVs could be candidates, should the company take action at all. If the patent ever applies to real-world products, however, we'll have an inkling as to how the bendy shapes came to be.

Sometimes, a patent grant is less about the technology itself than what it could mean for others. Case in point: a newly granted Apple patent for a "mini-SIM connector." The design complements earlier work and represents a straightforward approach to a SIM slot that prevents damage from inserting the card the wrong way and ejects the card through a plunger system. By securing the patent, however, Apple gains a bargaining chip in phone technology disputes, especially for SIM-related tussles; companies are less likely to start a fight if Apple can return fire. The claim doesn't give Apple a lock on subscriber modules by any means, but it could lead to other adopters treading carefully.

Sirius XM's first Onyx radio showed its face three years ago. For the technology world, that might as well have been eons; that makes it something of a relief to see an update, the Onyx EZ, going through the FCC for approval. The differences that justify the 1950's-era model suffix are tougher to identify, however. Both the current and future Onyx models revolve around superficially identical feature sets that include a PowerConnect FM transmitter to streamline in-car setup, station preset controls and quick access to both traffic and weather. If there's more lurking underneath the EZ, we'll have to wait for an official launch, whether it's at a Las Vegas trade show or later into the year.

Tablet lovers who've been eying Microsoft's elaborately named Surface with Windows 8 Pro may be one step closer to getting it in their hands now that a mystery Microsoft tablet, the 1514, has swung through the FCC's approval process. While there's no neon lights advertising the slate's identity, it's described as running Windows 8 -- the current Surface appeared at the FCC clearly labeled as a Windows RT device. The 1514 number is also just two digits away from the 1516 of the Surface we can buy today. Prospective buyers hoping for unadvertised wireless features won't get them, as there's just 802.11n WiFi and Bluetooth, but we don't think they'll mind. If the hardware truly represents the high-end Surface variant, an FCC appearance means one less obstacle to the planned January release.

Most software has to be designed around a presumed viewing distance, whether it's up close for a smartphone or the 10-foot interface of a home theater hub. Apple has been imagining a day when the exact distance could be irrelevant: it's applying for a patent that would automatically resize any content based on viewing distance. By using a camera, infrared or other sensors to detect face proximity through facial recognition or pure range, the technique could dynamically resize a map or website to keep it legible at varying ranges. Although the trick could work with most any device, the company sees that flexibility as most relevant for a tablet, and it's easy to understand why -- iPad owners could read on the couch without needing to manually zoom in as they settle into a more relaxed position. There's no knowing the likelihood that Apple will implement an automatic scaling feature in iOS or OS X, let alone make it the default setting. If the Cupertino team ever goes that far, though, we'll only have our own eyesight to blame if we can't read what's on screen.

HP couldn't help but harsh the mellow of cutting-edge workers when it revealed the ElitePad 900 wouldn't ship until January. Still, there's less chance of any setbacks now that we know the FCC has rubber stamped the Windows 8 tablet. The version passing through the agency is a 3G model for mobile road warriors and touts the 850MHz, 1,700MHz and 1,900MHz bands we'd expect to for HSPA on AT&T, T-Mobile and Canadian networks. Few other surprises exist; we're mostly happy to know that NFC exists alongside dual-band 802.11n WiFi and Bluetooth 4.0. No, the approval won't be much consolation to the suits and ties wanting a tablet of their own as of yesterday, but it should be a relief to IT managers planning a much more creative use of the company budget in 2013.

Apple's iPad mini and 4th-generation iPad didn't arrive alone. In the company's time-honored tradition, it has timed the FCC filings for both devices to show up alongside the products themselves. Each iOS tablet has been approved in both singular WiFi and dual cellular editions: the iPad mini has appeared as the WiFi-only A1432 as well as the A1454 and A1455 for worldwide HSPA+, EV-DO and LTE coverage, while the full-size iPad has been cleared in directly paralleled A1458, A1459 and A1460 versions. Not surprisingly, the frequency range matches that of the iPhone 5 and suggests that we're dealing with the same Qualcomm MDM9615 chip. We'll know more once the two iPads are in our hands and those of teardown artists, but for now you can explore Apple's regulatory gymnastics in full at the source links.

If you're one of the more daring (or foolhardy) photographers out there, you've tried camera tossing: hurling your camera into the air in the hopes that a timed shot will catch either a unique perspective or an artistic spin. Nikon might not want to stop those shooters from throwing caution to the wind, but its recently published Japanese patent would at least keep those throws to a minimum. Cameras based on the patent could use a built-in accelerometer not just for timing the shot, but to brace for a fall by covering the lens and retracting its barrel on the way down. In theory, the photographer gets a perfect aerial portrait without all the guesswork and a minimum of damage. Call us skeptical that we'll ever see the patent reach a shipping product, though -- even if it was limited to rugged cameras, a mode built almost exclusively around voiding the warranty probably wouldn't sit well with Nikon's accountants.

We already know what some of you are thinking, but that doesn't change the reality on the ground: Apple has been granted a design claim patent for a "portable display device" that looks a whole lot like the original iPad. Filed just a day before the big reveal in 2010, it's both specific to the tablet and cites additional references dating as far back as the early 1990s. The claim likewise includes elements that transpired between the filing and the granted date, such as a certain legal squabble that carries on to this day. While we can't say we're enthusiastic for what might follow from the patent becoming official -- we know Samsung isn't, despite victories in the tablet space -- it does give Apple one more tool for arguing that its total iPad design is unique, not just the individual components.

No more shall lefties wanting Google Glass toil under the oppression of right-handed overlords. Not if Google's newly granted design patent is an indication, at any rate. The filing simply puts the eyepiece on the other side for those who are either naturally left-inclined or just that much opposed to the optical status quo. There's no guarantee Google will be so accommodating when Glass reaches the general public, although we're hopeful: when early adopters are already paying a small fortune to leap in, it wouldn't hurt to produce a batch for left eye use and give the more committed southpaws among us the freedom they've craved since Google I/O.

Hopefully AT&T subscribers weren't spooked when the Nokia Lumia 920 first passed through the FCC in only its non-US guise, and its lower-end 820 cousin only as the (currently unofficial) Verizon-ready Lumia 822. The two Windows Phone 8 flagships have had follow-up approvals in GSM versions that are unmistakably destined for AT&T and Canadian carriers. Never mind the slightly distracting RM-820 model number on the Lumia 920; it reveals the 920's distinctive curved design, 700MHz LTE in AT&T's range and AWS-based LTE for both AT&T as well as its Canadian neighbor. The Lumia 820 is equally identifiable as the RM-824, even if it limits the LTE access to AT&T's network. We haven't seen any shocking revelations from either device, although we weren't expecting any from phones that hew so closely to the original templates. The filings mostly set expectations for Microsoft's October 29th event -- now that the likely stars of the show are cleared to make their appearances, the companies involved should breathe more easily.

If you're Toshiba, what do you do when you're looking to goose interest in the Excite 10 tablet? Roll out a quick follow up, of course. Accordingly, the FCC has just recently cleared a refreshed tablet, the AT300SE, that the Bluetooth SIG suggests will be called the Excite 10SE in North America. As shown, it's a European-spec WiFi model that gives away little by itself. It's when we combine this with the Bluetooth listing and speed tests that a clearer picture of the upgrade emerges -- there's been an AT300SE in GLBenchmark's performance charts that we've seen running Jelly Bean (unavailable to current Excites) on top of what looks to be the familiar 1,280 x 800 display and 1.3GHz Tegra 3. While there may be other surprises lurking in areas the tests can't reach, the documents point to a quick nip-and-tuck from Toshiba to keep tablet sales afloat rather than a full overhaul.

Just in case you thought Nokia's Lumia 822 for Verizon was an illusion, the FCC has given us good (if not quite smoking gun) evidence that it's tangible. A filing at the agency shows a device that's only listed as the RM-845 on the surface, but has Verizon's CDMA and LTE bands, measurements very close to those of the GSM-based Lumia 820 and a microSD slot that you wouldn't find in a Lumia 920 variant -- short of a surprise new model, there's little beyond the 822 that would currently fit the bill. Those disappointed that it's not a higher-end Lumia might take some consolation in seeing both the expected NFC as well as quad-band HSPA 3G for world roaming. Between the FCC and earlier photos, fans are really just left waiting for Verizon to make this new piece of its Windows Phone revival official, whether it's on October 29th or some other date.
